Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling oil pressure in internal combustion engine systems are inadequate in providing precise and dynamic lubrication and cooling, especially in advanced vehicles, leading to inefficiencies and increased operational costs.
Innovation Solution
A method that involves receiving indications of upcoming vehicle operating situations, determining expected changes in engine operation, and adjusting oil pressure in the oil pump to ensure precise lubrication and cooling by predicting future oil pressure needs based on current conditions and route information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current oil pressure control methods are used, then the system is simple to operate, but the lubrication and cooling precision is insufficient
Solution Approach 1:
The system receives indications of upcoming vehicle operating situations in advance and determines expected changes in engine operation before they occur. The oil pressure is adjusted proactively based on predicted future needs rather than reacting to current conditions, enabling precise lubrication and cooling alignment with future engine demands.
Solution Approach 2:
The oil pressure control system transitions from static to dynamic operation by continuously adapting to changing vehicle operating situations. The control unit adjusts oil pressure in real-time based on predicted engine operation changes, route information, and current conditions, enabling precise and flexible lubrication management.
2Reliability
If oil pressure is adjusted dynamically, then lubrication and cooling are optimized, but the response time may be delayed
Solution Approach 1:
The system performs preliminary actions by receiving indications of upcoming operating situations and determining expected engine operation changes before they actually occur. This advance preparation ensures that oil pressure adjustments are made in time to align with future engine demands, eliminating delays in lubrication response.
3Productivity
If oil pressure is continuously adjusted, then engine performance is optimized, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts oil pressure based on actual and predicted engine operating conditions rather than maintaining constant pressure. The control unit continuously adapts oil pressure to match changing vehicle situations, route information, and engine demands, optimizing performance while avoiding unnecessary energy consumption from excessive pressure maintenance.
